DE TACHAB LE TOOL-HANDLE Specification. of Letters Patent.

Application filed; June 6, 1908.

Patented. Nov. 17. 1908.

Serial No. 437,045.

To all whom it may concem:

lle it known that I, HENRY FRANK POCAN, a citizen of the United States,residing at Stephenson, county of Menominee, and State of Michigan, haveinvented certain new and useful Improvements in Detachable Tool-Tlandles, of which the following is a specification.

My invention relates to tool handles, and particularly to that class inwhich the tool and handle are made detachable.

The object of my invention is to provide a handle as mentioned, whichwill securely and rigidly hold the properly shaped shank of a toolsuchas a hoe, spade, etc., in such a manner that the tool may be quicklyand readily detached if desired and anotherpne secured in its place justas readily and quickly.

A further object of my invention is to provide a device as mentioned,which shall be strong and durable, simple of construction, hence of lowcost to manufacture.

With these objects in view, my invention consists generally in anordinary tool handle the forward end of which is provided with alongitudinal recess and a member hingedly mounted in said recess, saidmember being provided with a plurality of lugs.

My invention further consists n a tool shank properly shaped andprovided with a plurality of transverse slots, the recess in said toolhandle being adapted to receive said shank, and the slots in saidshankbeing adapted to receive the lugs on said hin ed member of the toolhandle, said shank being locked in position by a sleeve.

My invention will be more readily understood by reference to theaccompanying drawings forming a part of this specifica- Figurel .a sideelevation of my device in its preferred form, Fig. 2 is a section on"substantially the line ofFig. 1, Fig. 3 is a detail perspective view ofmy device, Fig. l is a detail sectional view of the handle portion of mydevice, the tool shank being shown in dotted lines, and Fig. 5 is adetail of the tool detached. I

Referring now to the drawings, 1 indicates the ordinary handle pf atool, such as a spade, hoe or the like. Extending from the lower end 2of the handle 1, is a longitudinal recess 3 which is of any suitablelength. The recess 3 may be of any suitable shape in cross ect-lollother than circular. but as I have shown in the accompanying drawings,

is preferabl rectangular. Hingedly secured preferably by a bolt 4, tothe member '1 in the recess 3' preferably near the rearward end of saidrecess as at 5, is a member 6. Said member 6 is of substantially thesame length and width as the recess 3 and preferably of a thicknessequal to half the depth of said recess.- The member 6 is provided with aplurality of transversely extending lugs 7, said lugs being of anysuitable shape. The rearward portion of .the shank 8 of the tool to beused is of substantially the same shape as the member 6, and is providedwith a plurality of transverse slots 9, said slots being so positionedand shaped as to receive the lugs 7 on said member 6.

In attaching the tool to the handle, the shank 8 is placed in the bottomof the recess 3, as shown in Figs. 2 and 3 and in dotted lines in Fig.at in the drawings, in such a position as to receive the lugs 7 of themember 6. To facilitate securely locking said members together when inposition, I provide a preferabl sleeve 10, said s eeve being adapted tofit snugly, hence may be locked to the slightly tapered end portion 11of the handle 1.

It is obvious that withthis sort of a handle, any tool having its shankproperly shaped and slotted as described, may be as rigidl secured tosaid handle as though it were ormed integrally therewith.

Havin'g described my invention what I claim as new, and desire to secureby Letters Patent, is:

1. A tool having a shank, in combination with a tool handle having alongitudinal recess, a member hingedly mounted in said recess,aplurality of lugs on said hinged member, said shank being provided withcorresponding slots to receive said lugs and a sleeve holding said toolshank and hinged member in locked position in said recess, substantiallyas described.
